3 Claims. l

This invention relates to a toi gun of the compressed air type which will shoot a small projectile such as a dried pea.

An object of my invention is to provide a novel projectile shooting toy gun including a magan zine which holds a plurality of small projectiles, each of which can be fed into the gun at a time.

Another object of my invention is to provide a novel projectile shooting toy gun in which each projectile is fed into the gun on manual movement of a feed sleeve.

Still another object of my invention is to provide a novel projectile toy gun which includes a restrictor in the barrel, this restrictor being adjustable to hold the projectile until air pressure has been exerted against the projectile b" the gun.

A feature of my invention resides in the novel means to manually adjust the restrictor in the barrel of the gun so that a greater or less force will be required to eject the projectile.

Still another feature of my invention is to provide a novel toy gun of the character stated in which the restrictor consists of a flexible element such as rubber or plastic or a covered spring.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing:

Figure 1 is a side elevation of my toy gun with parts broken away to show interior construction.

Figure 2 is a fragmentary side elevation of the barrel of the gun with parts broken away to show the feeding mechanism.

Figure 3 is a fragmentary longitudinal sectional View of the gun barrel showing the projectile in position to be ejected.

Figure 4 is a fragmentary longitudinal sectional view of the outer end of the gun barrel showing the restrictor.

Figure 5 is a fragmentary longitudinal sectional view of the gun barrel showing a modiied form of restrictor.

Figure 6 is a fragmentary longitudinal sectional View of the gun barrel showing still another modifled form of restrictor.

Referring more particularly to `the drawing the toy gun I, is of the compressed air type and consists of an air chamber 2, in which a piston 3, moves under the pressure of the spring i. The piston 3, is retracted manually by means of the rod 5, which projects from the back of the gun and this rod is releasably engaged by the trigger controlled pawl 6.

As thus far described the construction of the gun is quite usual and the details of the aforesaid construction form no part of my invention other than the combination of the subsequently described mechanism with an air gun.

A barrel 'I is xedly mounted on the outer end of the cylinder 2 and forms an extension of this cylinder. The barrel 'I is preferably mounted in the cylinder 2 by means of a block 8, which has a reduced bore El therein to increase the velocity of the air. A tube Il] is mounted in the barrel l', and is adjusted longitudinally in the barrel in the following manner.

A pin II projects from the tube lll and this pin ts in the bayonet slot I 2 to any one oi' several adjusted positions. A restrictor I3 is xedly attached to the inner end of the tube Il), and this restrictor may consist of a rubber tube as shown in Figures 2-4 inclusive or it may be a sponge rubber block Ill as shown in Figure 5, or a metallic spring I6 surrounding a rubber ring as shown in Figure 6. The tube I0 in its longitudinal movement elongates the restrictor thus constricting the passage therethrough or compresses the restrictor as in the case of the sponge rubber block I5 which also restricts the orice through the block.

One end of the restrictor I3 is secured to the tube I6 while the other end thereof is xedly attached to the feed block I1. This feed block is xedly mounted in the rear end of the barrel 'I. A feed sleeve I 8 is constantly urged outwardly by the spring I9 which lies within the bore 9.

A magazine 20 is mounted on top of the barrel 7 and a number of projectiles 2| (which may be dried peas) are fed into the magazine. The cork 22 closes the outer end of the magazine and retains the projectiles. The feed sleeve I8 is retracted manually by means of the pin 23 which moves in the slot 24 in the barrel 1. When the sleeve I8 is retracted a pellet 2I can drop into the tube I3 as shown in Figure 2. When the pin 23 is released the spring I9 presses the tube I8 forwardly and moves the pellet into the restrictor I3 as shown in Figure 3. The projectile is .now ready to be ejected and the piston 3 is pulled backwardly after which the trigger is pulled and air pressure acting against the projectile restrained in the restriction of the restrictor I3 will force the projectile out through the tube I0. The projectile is held against the restrictor in the same manner in Figures 5 and 6, that is, the same sleeve I8 presses the pellet into the restrictor element. If it is desired to shoot the pellet with greater force the restrictor element I3 is further constricted by manually adjusting the tube IIJ.

The operation of my toy gun is as follows: The magazine 2D is lled with dried peas, and the cork 22 then closes the outer end of the magazine. The piston 3 is now pulled backwardly in the cylinder 2, thus drawing a charge of air into the gun. The restrictor I3, l5, or it, is adjusted as required by the user by moving the pin il, into the desired notch l2. The pin 23 is now pulled rearwardly by the operator, thus permitting one pea to drop into the rear end of the tube I0, and release of the pin 23 will push this pea against the inner end oi the restrictor. The gun is now red, and the pea is ejected from the end of the tube I0, by the force of the air compressed ahead of the piston 3.

Having described my invention I claim:

1. In a gun operated by compressed air, said gun having a compressed air chamber, a barrel extending from the chamber, an expansible annular restrictor mounted in said barrel, against which a projectile can rest, and means engaging the restrictor to adjust the diameter of the same, a magazine for projectiles mounted on the barrel, said magazine opening into the barrel between said chamber and the inner end of the restrictor, a spring pressed sleeve in the barrel, said sleeve engaging the projectile to press and hold the projectile against the restrictor, and manual means on the sleeve projecting from the barrel to retract said sleeve.

2. In a gun operated by compressed air, said gun having a compressed air chamber, a barrel extending from the chamber, an expansible annular rcstrictor mounted in said barrel, against which a projectile can rest, and means engaging the restrictor to adjust the same, a magazine for projectiles mounted on the barrel, said magazine opening into the barrel between said chamber and the inner end of the restrictor, a spring pressed sleeve in the barrel, said sleeve engaging the projectile to press the projectile against the restrictor, and manual means to retract said sleeve to feed a projectile into the barrel, said manual means comprising a pin extending from the sleeve, said barrel having a slot therein through which the pin projects.

3. In a gun operated by compressed air, said gun having a compressed air chamber, a barrel extending from the chamber, an expansible annular restrictor mounted in said barrel, against which a projectile can Test, and means engaging the restrictor to contract the same, a magazine for projectiles mounted on the barrel, said magazine opening into the barrel between said chambei' and the inner end of the restrictor, a spring pressed sleeve in the barrel, said sleeve engaging the projectile to press the projectile against the restrictor, said barrel having a slot therein adjacent the sleeve, and a pin extending from said sleeve and through said slot.
